12.9 = x + 7.1
subtract 7.1 from both sides to isolate the variable, x.
5.8 = x
5.8 is your answer.
Answer:
°
Step-by-step explanation:
For the upper left angle, we know that they are supplementary, so we can find the first angle of the triangle by
![180-130=50](https://tex.z-dn.net/?f=180-130%3D50)
For the bottom right angle, we know that they are supplementary, so we can find that angle by
![180-134=46](https://tex.z-dn.net/?f=180-134%3D46)
As a triangle has 180 degrees, we can subtract the values of the other two angles to find the final upper right angle.
![180-50-46=84](https://tex.z-dn.net/?f=180-50-46%3D84)
Lastly, The upper right angle and x are supplementary so we can find x by subtracting the angle from 180
![180-84=x\\x=96](https://tex.z-dn.net/?f=180-84%3Dx%5C%5Cx%3D96)
Answer: 39$
Step-by-step explanation: calls=x x=30 30*.05= 1.50 40.50-1.50= 39$
<h2>39/6 = 6.5</h2><h2 /><h2>6 hours 30 minutes</h2>
Multiply the variable k times 4 would give you 4k.
Then cross multiply 14x8 = 112
Therefore, you would have 4k = 112.
Divide 112 by 4 to get your answer!
